A Wideband CP Crossed Slot Antenna Using 1-λ Resonant Mode with Single Feeding
This communication proposes to use the 1-λ resonant mode of slot radiator with single feeding for bandwidth enhancement. The impedance of a simple slot radiator is studied using computer simulation. Since operating the slot radiator in the 1-λ resonant mode requires a longer slot length, a large square slot is used at both ends of the slot to reduce the required slot length. The results of the stu
